Ahh so you was also part of it, here is updated patch:

[PATCH -tip] x86: thread_info.h moving comment to where it should be

By mistake commit 3351cc03 forget to move following comment along
with INIT_THREAD_INFO :

 "preempt_count needs to be 1 initially, until the scheduler is functional."

Moving comment back to right place where preempt_count is setting to 1

Also by mistake commit 2052e8d4 forget to fix extra line which is not required.
Removed that extra line.
